Subject Re: Cluster anti-affinity
Date Tue, 26 Sep 2017 21:57:16 GMT
Hi Ivan,
I don't think cloudstack offer cluster anti affinity and i'm sure i would
be in favor of introducing another anti affinity level, because it would
expose cluster notion to your cloud user.

Although, look at the vm provisionning strategy config, their should be a
deployment strategy that would spread account vms across pods or clusters,
or prefer pod/cluster proximity. I think this could help you.

Regards,
